Audi R8 e-tron is back in the spotlight. In June 2012, the German supercar set a new lap record at the Nurburgring, completing the course in 8:09.099. The car was supposed to go into production towards the end of the same year, but in October Wolfgang Dürheimer, Audi R&D chief, ordered the project to be halted, because of the high cost of batteries (or maybe for “performance reasons”?).
It now seems that the R8 e-tron project has been put back on the list and has begun a new phase of testing, but it’s still not certain if the model will enter production. The e-tron now benefits of the same aesthetic features of the R8 MY 2013 and will soon employ new components to lower the drag coefficient from 0.35 to 0.27. In addition, Audi is developing an e-tron version with rear wheel drive, equipped with two electric motors producing an output of 380 HP and peak torque of 818 Nm, which push the 1780 kg of the car from 0 to 100 km / h in just 4.2 seconds. The battery pack, weighting 577 kg, will be place at the bottom in order to lower the centre of gravity.
Audi is trying to further reduce the overall weight of the car, using shock absorbing unit with reinforced fibre glass springs, titanium wheel hubs and aluminium and carbon fibre antiroll bar. These components will also be used in the next generation of Audi R8, to keep industrial costs down. It is still unclear when the car that travels around 160 km with fully charged batteries, will be marketed and how much will be costing. Audi R8 e-tron might become a sort of ever evolving laboratory on wheels rather than a standard vehicle.
